Syrian government airstrikes on a residential neighborhood in a rebel-held town killed over 40 people and wounded at least 100 others including many women and children, international watchdog Human Rights Watch said Thursday, August 16, Associated Press reported.

The strikes on the town of Azaz in northern Syria a day earlier leveled the better part of a poor neighborhood and sent panicked civilians fleeing for cover. So many were wounded that the local hospital locked its doors, directing residents to drive to the nearby Turkish border so the injured could be treated on the other side.

Reporters saw nine bodies in the bombings' immediate aftermath, including a baby.

Human Rights Watch, which investigated the site of the bombing two hours after the attack, put the number at over 40.

"This horrific attack killed and wounded scores of civilians and destroyed a whole residential block," said Anna Neistat, the group's acting emergencies director. "Yet again, Syrian government forces attacked with callous disregard for civilian life."

HRW said two opposition Free Syrian Army facilities in the vicinity of the attack might have been targets of the Syrian aircraft.
